Fresh water tank not filling to capacity

[Lowrider mike]

I have a Stealth trailer that is supposed to have a 100 gal fresh water tank. Seems like the most that i can put in is 60 gal. Is this common?

I looked up the specs on the Stealth trailers and didn't note a unit with anywhere near a 100 gal fresh water capacity. 40ish mostly. Is yours a custom build? 100 gallons is ~800 lbs, that's quite a lot of weight to be dragging about. Otherwise, when you get to the *60 gallons are you seeing water come out the overflow, if so you either have a hole in your 100 gallon tank 6/10ths of the way up the tank, the overflow is mounted 6/10ths of the way up or you have a 60 gallon tank? If not and keep in mind this is not likely, but possible.( I've seen stranger) if there is no overfow and no venting of the tank ie, no valves are open, when the air in the tank is compressed to the point it is equivalent to the pressure of the incoming flow the incoming flow will stop. Too, if you're using one of those flow meters which attach to the hose, they're notoriously inaccurate. If you can see and access the tank, measure it. (Height • length • width) • 7.48, that's your tanks capacity in gallons.
